The National Weather Service in Grand Rapids has issued a Beach Hazards Statement...which is in effect until 2 PM EDT this afternoon. * HIGH WAVE ACTION... STRONG CURRENTS AND DANGEROUS SWIMMING CONDITIONS EXPECTED. * STRONG STRUCTURAL CURRENTS EXPECTED * STRONG LONGSHORE CURRENTS EXPECTED * RIP CURRENTS EXPECTED * LOCATION...BEACHES FROM St. Joseph to Grand Haven North Beach in South Haven... Holland State Park... Muskegon State Park... Mears State Park in Pentwater... Stearns Park in Ludington. FOR SOUTH FLOW USE: * OVERVIEW/POTENTIAL IMPACTS...Northwest winds of 15 to 25 knots will continue to cause waves of 3 to 5 feet into early this afternoon before subsiding. Waves of this height will pose a hazard to swimmers. PRECAUTIONARY/PREPAREDNESS ACTIONS... High Wave Action makes swimming difficult and can tire even a strong swimmer quickly. Structural currents form along piers where longshore currents and wave action flow into the structure. Structural Currents can sweep you out into deeper water along the pier structure. A longshore current is a lake current that moves parallel to shore. Longshore currents can be strong enough to Prevent swimmers from being able to keep their feet on the bottom... making it difficult to return to shore. Rip currents are powerful channels of water flowing quickly away from shore...which occur most often at low spots or breaks in sandbars. Rip currents can sweep you into deeper water. && $$ WEATHER.GOV/GRR
